Help please with Japanese silver sake cups

[Drb1643]

Here’s pictures of 3 different cups. One I recognize as the navy proficiency award but the other two are different. Can any of the members here help me identify the other two?
Thank you very much,
Tom

Difficult kanji because they are in the old seal-script. I cannot make out that second kanji .... and I have no idea what "brew" has to do with this .... unless it's for "sickbay alcohol punch."

Thank you both very much. I’m sorry I didn’t realize the picture was blurry and hard to read the kanji. Here is another shot.

Thanks Nick!! HOLY COW. I saw the Taisho date so tried to read the entire thing from left to right. I guess I should have read from center mass:
